• e is does not satisfy the Error interface.

Types

type Code

type Code int

Code represents a common keyvalue error.

func (Code) New

func (c Code) New() error

New returns a new error with error code c. The error satisfies the Error interface.

func (Code) String

func (c Code) String() string

String returns a description of the error with error code c.

func (Code) Wrap

func (c Code) Wrap(e error) error

Wrap returns a new error with error code c and cause e. The error satisfies the Error interface.

type Error

type Error interface {
	// Code returns the code associated with this error.
	Code() Code
	// Error returns a string description of the error.
	Error() string
}
